Timber is tanalised through a pressure treatment process that involves placing the wood in a vacuum chamber, where preservatives are injected under high pressure. This effectively forces the chemical preservatives deep into the wood fibers, enhancing its resistance to decay, insects, and moisture. The most common preservative used is copper-based, which helps prolong the life of the timber for outdoor and structural applications. After treatment, the timber is typically dried to ensure it is ready for use.
What else can I help you with?
Will tanalised timber twist in hot dry conditions?
no
Can tanalised wood be painted?
TANALISED timber relates to timber that has been industrially treated with TANALITH preservative under vacuum in an enclosed treatment vessel. The preservative manufacturer, Arch Timber Protection, has a website at www.archtp.com with a Consumer Information Sheet which contains advice regarding compatible glues for TANALISED E pressure treated timber. A range of glues are advised, depending on the end use of the treated timber.
What are the blue marks on tanalised timber?
The blue marks on tanalised timber are caused by the copper-based preservative treatment used to protect the wood from decay and insects. These marks are a normal occurrence and do not affect the structural integrity or performance of the wood.
Will tanalised timber split?
Tanalizing, an impregnation with a copper chrome arsenate, only improves the timber's durability. Whilst the timber is wet, its splitting tendency will be reduced.
What is tanalised timber?
Tanalised timber is wood that has been treated with a preservative solution, often involving copper-based compounds, to enhance its resistance to rot, decay, and insect damage. This process, known as tanalisation, helps extend the lifespan of the timber, making it suitable for outdoor use in structures like fences, decks, and garden furniture. The treatment typically gives the wood a greenish hue, indicating its preservative content. Tanalised timber is popular in construction and landscaping due to its durability and cost-effectiveness.
Does tanalised timber protect from dry rot?
It will help, but the best way to prevent dry rot is to keep timber dry and to ensure it gets enough ventilation.
Is tanalised timber harmfull to pets?
Tanalised timber, treated with preservatives to resist rot and insects, can be harmful to pets due to the chemicals used in the treatment process, such as copper, chromium, and arsenic in older formulations. While modern treatments have reduced toxicity, ingestion of wood or exposure to treated surfaces can still pose risks. It's best to ensure pets do not chew on or ingest tanalised timber and to consult a veterinarian if you have concerns about exposure. Always monitor pets around treated wood products.
What will happen to your health if you burn tanalised timber in an open fire?
Tanalised timber refers to wood that has been industrially treated using a controlled vacuum pressure process with Tanalith preservative. Tanalised and Tanalith are registered trade marks of Arch Timber Protection, and may not be used to describe other formulations.Tanalith C preservative contains chromated copper arsenate (CCA). In Europe, the use of Tanalised C pressure treated timber was restricted in 2006, and its replacement there is Tanalised E pressure treated timber, which contains copper and triazole biocides - which are commonly used to protect food crops.The options for disposal of Tanalised wood are dependent on the formulation of Tanalith preservative that the timber was treated with, which can be identified by analysis. The Code of Practice in Related Links gives recommended advice on how treated timber can be disposed of effectively.Tanalised E may be burned in approved industrial incinerators, but should not be burned in open fires or home wood burners. Please see the Related Link for more detailed information.When burned, Tanalised C or CCA treated timber releases toxic chemicals into the air and concentrates them in the ash. The treatment of this timber may incorporate Copper, Chrome and Arsenic. These can all be classed as heavy metal toxins. Symptoms will vary depending on the degree of poisoning but can include:loss of appetite,nausea,vomiting,diarrhoea,skin tingling,cramping of muscles,seizures,hearing loss,sleepiness,confusion,headaches,fainting,dizziness.
Can you get arsenic poisoning from handling Tanalised wood?
Tanalised timber refers to wood that has been industrially treated using a controlled vacuum pressure process with the Tanalith preservative.Tanalith C preservative contains chromated copper arsenate. In Europe, the use of Tanalised C pressure treated timber was restricted in 2006, and its successor in this market is Tanalised E pressure treated timber, which contains copper and triazole biocides.Timber treated with any Tanalith preservative is resistant to leaching but should be handled with care and any exposed skin is recommended to be washed before eating, drinking or going to the toilet. Avoid handling treated timber that is wet.See the Related links for more information.
Is tanalising an oil based or water based wood treatment?
TANALISED pressure treated timber has been impregnated with TANALITH E, a waterborne product.
Is cutting tanalised timber safe?
Cutting tanalised timber, which is treated with preservatives to protect against rot and pests, can pose health risks due to the chemicals used in the treatment. It is essential to wear appropriate personal protective equipment, such as gloves, goggles, and a mask, to minimize exposure to potentially harmful dust and vapors. Additionally, ensure proper ventilation when cutting the timber to further reduce risks. Always follow local guidelines and safety recommendations when handling treated wood.
Is tanalised timber safe around koi pools?
Tanalised timber, which is treated with preservatives to prevent rot and insect damage, is generally considered safe for use around koi ponds. However, it's essential to ensure that the chemicals used in the tanalisation process are non-toxic and safe for aquatic life. Always check for any specific product guidelines and consider using timber that is certified safe for aquatic environments. Regular maintenance and monitoring are also important to ensure the safety of the koi.
